They were in the initial list I had, and then I went through and excluded a number of cleanup issues. I guess I excluded too many. I'll add these two back in.

Yes, except for [JDK-8303748](https://bugs.openjdk.org/browse/JDK-8303748) which I excluded because it is a build issue that isn't relevant to application developers.

> Lastly, I was of the opinion that backports are not a part of the release notes, but it seems that [JDK-8313324](https://bugs.openjdk.org/browse/JDK-8313324) is still added?

Prior to this release, we wouldn't have included backports. However, with the change to the stabilization process such that all fixes first go into master and are then backported to the stabilization release, we would miss actual fixes that are first delivered in this release if we didn't consider them. Note that we need to use the base bug ID for backports that were first fixed in jfx21.
